security made simple
I work two support queues. In one, readers email when a lab created output or did not match the screenshots within the book, the other, my extended family calls because the smart doorbell logs visitors an hour before they arrive, or the Wi-Fi is "broken" while every light on the router looks fine...
A tool's failure is advisory because a human still reviews the output before anything happens. An agent's failure is operational because the bad output is the action...
Welcome back to the Basics Series. In Basics Series - #3 we compared the firewall market, picked OPNsense for the lab, and installed it as a VM. In Basics Series - #4 we worked through the traditional vs. transparent-bridged decision and I promised a configuration walkthrough. This is that post...
This installment goes in a different direction. Where the last post zoomed all the way in — past the running host, past the alert, down to a single line of source...stepping away from individual controls entirely and asks about the distributed, multi-platform enterprise the cloud produced.
We've climbed through the rings of the architecture... This installment goes further upstream than any of them. It steps back to the code itself — and asks how you find the flaw while it's still cheap to fix and it hasn't shipped yet. That's the domain at the heart of Application Security Testing.

This installment does something different. Every domain we've covered so far — even the unglamorous hygiene loop — was, at bottom, an attempt to keep the bad day from arriving. This one starts the morning after it did...
My lab runs Debian 13 as the primary environment, so when a 356-page Ubuntu book landed on my desk, my first instinct was to skim it, nod politely... Instead I read the whole thing — and I'm giving it five stars...
I've been working through the second edition of the Cybersecurity Architect's Handbook's "secret menu" one domain at a time...the controls that still mean something after everything else has fallen. This installment does something different...it looks down at the ground all of them are standing on.
Every control we design as architects ultimately serves one of two questions. Who is allowed to do what — and is the data still protected ... Access control answers the first. Data protection answers the second. Together they form the innermost ring of a defense-in-depth architecture...
Every query a device makes is a statement of intent — what it wanted to reach, when, and how often — and once you're logging them, you're no longer just blocking bad names. You're watching behavior....
Before we get into the core of the article — a quick, time-bound note. Packt is sponsoring a giveaway on my LinkedIn channel...This post moves to the first place that thinking touches wire: Category 2, Network Security Controls...
"Instead of just rehashing abstract theory, it bridges the gap between high-level security principles and real-world execution. It's practical, actionable, and a great tool for anyone designing or engineering modern infrastructure."
